Be it known that I, MATHnw STEINBRECHER, a citizen of the United States, residing at New York, in the county of New -York and State of New York, have invented certain new and useful Improvements in Covering Radiator- Pipes or Risers, of which the following is a specification.

The present invention pertains to improvements in covering radiator-pipes or so-called risers especially in public buildings, with the object to protect surrounding objects against the heat of the pipes and prevent a person that may involuntarily come in contact therewith from being injured orscalded.

Another object of my improvements is to save theasbestos covers generally used with the risers from being destroyed by children.

My improvements consist in the arrangement of a mantle or casing of sheet metal, as galvanized sheet-iron or the like, and particularly in the construction of such mantles or casings.

As the risers or radiator-rapes in various buildings are arranged in dierent forms, some having elbow-pipes and joints at different points, generally at their lower ends, the casings must be made to conform with the particular shape and size of the risers. In such cases where the riser is equipped with elbows, joint-pieces as well as branch pipes at its bottom, I prefer to arrange for the said lower part a casing of preferably square or rectangular shape, and for the Lipper straight part of the riser a casing which in its shape substantially conforms with that of the jointfianges, which generally have the shape of'an ellipse. As it will be also necessary that this casing surrounding the riser shall be neat, so as not to spoil the appearance of the room in which it is used,I form the substantially square base part of the casing at its upper part, so that it will gradually adapt itself to the octagonal shape of the upper reduced section, which I claim as one of the most important features of my invention.

A further valuable feature of the present improvements is the manner of joining the walls of the casing with each other, which will be hereinafter fully specified.

My invention will be fully understood from the accompanying drawings, in which similar reference-letters denote corresponding parts, and in which- Figure l is an elevational view of my improved casing; Fig. 2, an elevational view of the same at a right angle to that of Fig. 1. Fig. 3 is a vertical section through line fr of Fig. l. Fig. I is a top plan view thereof; Fig. a cross-section through line g/ y of Fig. l, and Fig. 6 aa partial sectional View of the joints in enlarged scale.

In the drawings one modification of the casing or mantle is illustrated. Here ci denotes the part of the casing that is adapted to be used for the lower portion of the riser equipped with branch pipes, joints, valves, elbows, &c., and which I will call the base-casing. As stated above, I prefer to form this casing square or rectangular and of any suitable sheet metal, preferably galvanized sheet-iron, although any other suitable shape, as octagonal or the like, may be chosen. In the example shown the casing is composed of four individual walls, the lower edges of which are Abent outward under a right angle to form a In the example shown the side walls c are tapered from a certain point, and one of the adjoining walls c perpendicularly thereto is bent inward to abut against the reduced edges of the side walls, and at another point the same is bent again perpendicularly upward.

A further reduction in the breadth of the base-casing is made by tapering one of the edges of the perpendicular upper part CZ of the front and rear walls and bending the upper parte of one of the side walls inward to abut against the said tapered edges and again perpendicularly upward, as at f. The width of the base-casing c at the point e is thus reduced from the wider size which it has at the bottom to that of the upper section Z of the casing. In order to transformthis reduced upper end of the casing a to an octagonal shape, the corners g, Zt, t', and j' are impressed in form of gores, and at the upper ends of the walls and at each corner gores Zi: it are cut out to form flexible tongs Z, which extend vertically upward. Owing to the gores g, z, Z, and y' at the corners, the Lipper part of the casing is thus transformed from its rectangular shape to an octagonal, the size of which IOO IOS

now conforms substantially with that of the upper casing to be mounted thereon.

The casingb may be constructed of any suitable sheet metal, galvanized sheet-iron, or the like, and may consist of individual walls joined together', or, as in the example shown, of a single piece of sheet metal.

`As stated above, I choose herefor an octagonal shape, since the same comes sufli-v ciently near the elliptical shape of the jointflanges of the riser. This octagonal shape is attained by suitably bending the walls of the casing.

The casing Z) may be of any; desired length and is adapted to be mounted on the top of the base a, or in case of a plain riserviz., a riser without any branch pipes, elbows, Sac.- the casing Z) only may be used and fixed directly to the floor. For ornamental purposes the top edges of this casing b may be folded down to form a crown b or the like.

The attachment of the upper casing I) to the top of the base ais attained by mounting it over the fleXibletongsZ and by connecting the latter with the walls of the casing by means of screw-bolts.

The connection between the walls of the casings is effected in the following manner: The edges m of one of the walls is folded inward in form of an S and the edges n of the adjoining walls are simply bent under an angle, so as to engage said S-shaped edges and be secured thereto by short screw-bolts 0. The base-casing ci may have all its walls joined in this manner, so that the seams formed by the folded edges will be located within the casing. In the example shown, however, I have shown the edges m of one of the walls folded substantially in form of a P and the edges a of the adjoining' walls simply bent under a right angle and engaged in said P edges, whereby an outer ornamental seam p is formed. The joints thus formed give a neat appearance to the casing and simplify the work.

For greater exactness it may be repeated that the main features of my improvements consist in the arrangement of a base and an upper casing, the manner of reducing and transforming the base to conform in size and shape with the said upper casing, and finally inthe method of forming the joints between the walls of the casings.

I wish it to be understood thatI do not restrict myself to the particular form of the arrangement shown, since any other shape may be devised for the casing without deviating from the spirit of my invention.

What I claim, and desire to secure by Letters Patent, is-w l. A casing or mantle of suitable sheet metal for radiator-pipes or risers of the character described, comprising two sections, a lower section or a base having a polygonal shape at its bottom and a reduced and transformed upper end, the reduction and transformation being made gradually by tapering and bending the walls and impressing the corners of the latter in form of gores, and an upper section conforming in shape with the said upper end of the lower section and adapted to fit thereon, the edges of the adjoining walls of each section being folded to form seam-joints, substantially and for the purpose as specified.

2. A casing or mantle of suitable sheet metal for radiator-pipes or risers of the character described, comprising' a base having a rectangular shape at its bottom and a reduced and transformed upper end, the reduction being made by tapering and bending the walls thereof and impressing the corners in form of gores, the said upper ends being' cut out at their corners to form fiexible tongs, and an upper section conforming in shape with and fitting upon the upper end of the base, substantially and for the purpose as specified.

In testimony whereof I afx my signature in presence of two witnesses.
